R = V / I
relative error = ΔR / R = ΔV /V + ΔI / I
V = 100 Volts ΔV = 5 volts
i = 10 Amp Δ i = 0.2 amp
relative error = 5/100 + 0.2 /10 = 0.07
% error = 0.07 * 100 = 7 %
relative error = ΔR / R = ΔV /V + ΔI / I
V = 100 Volts ΔV = 5 volts
i = 10 Amp Δ i = 0.2 amp
relative error = 5/100 + 0.2 /10 = 0.07
% error = 0.07 * 100 = 7 %
